Question 385206: It's been over 20 yrs since I've done this... please help with order of operations. Solve for s. I remember that I have to get the s by itself, but I am getting confused... the answer is supposed to be 1985, but I'm not getting that at all. Thanks.

%28s%2B25%29%2F2-100%2A10=5+
%28s%2B25%29%2F2-1000=5 Multiply 100 times 10
%28s%2B25%29%2F2+=+1005 Add 1000 to both sides
%28s%2B25%29+=+2010 Multiply both sides by 2
+s+=+1985 Subtract 25 from both sides
